| | | | | | | | | Reset the blksw and dithflag to 0 at the begining of each block. Otherwise blockswitching propagates over multiple frames even if block switching is not enabled for that frame. Also reuse rematflg. Originally committed as revision 9660 to svn://svn.ffmpeg.org/ffmpeg/trunk

| | | | | | | | | | | | | | | | I realized that the bug was not in the imdct routine but in the get_transform_coeffs. Fixed it. Code now uses the ffmpeg's imdct routines. All the mplayer's ac3 samples are decoded successfully. Also improved downmixing. Now all the downmixing coeffcients for channels are normalized such that the sum of coefficients used to construct the output for single channel never exceeds 1.0.

| | | | | | | | | | | | | | | More code cleanup. Window is now runtime generated. Fixed the bugs in rematrixing routine and in Decoding AC3 Bitstreams when coupling is in use. Still struggling to find out what affects the quality of the produced sound. Can anybody have a look at the imdct routines do_imdct_256 and do_imdct_512 and tell me whether it is the correctly implemented as described in standard.

| | | | | | | | | | | | | major code cleanup. correct implementation of imdct. implemented imdct for block switching also. when coupling is not in use all the ac3 streams are decoded correctly. but when coupling is in use there is a bug. i am currently finding the root of the bug. if anybody can help.

| | | | | | | | | | | | | | | | Latest commit. There is no error in parsing and or recovering transform coefficients. Double checked with ac3dec. Getting consistent results with the bit allocation routine and transform coefficients. The code is able to parse valid ac3 bitstreams without error from start to end. I have also implemented the imdct when block switching is not enabled. However, can anybody provide an insight into how to convert float samples to int16_t ? lrint is of no help cuz it produces output -1, 0 or 1 whereas the output should be between -32768 to 32767.

| | | | | | | | | | | | | | | | | | | | | | Removed _ from names Removed temporary storage for the exponents Removed ctx->samples Now each transform coefficients are stored in audio block as an array of transform coefficients for each channel added ctx->delay (output of later half of previous block) added audio_block->block_output(output of this block) I am still not able to produce the output. I checked the code twice completely. I am not missing anything in parsing or in bit allocation. Yet it throws error in getting transform coefficients sometimes. Can anyone review a code of get_transform_coeffs and help me debug it further. I think the error is in do_bit_allocation routine cuz get_transform_coeffs is dependent on the bit allocation parameters table. I have checked the bit allocation algorithm thoroughly and it is as defined in the standard. Tried everything and got stuck where to go further. Please help me.
